Yes, my friend you are right IEO's are safer than ICOs because of the management and control capability of a trusted third party — the host exchange. An ICO is something anybody can do and there is nothing to guarantee honesty and security. ICOs do not entail monitoring, whereas, to engage in an IEO, a project team is required to meet exchange requirements or else have their token rejected by the exchange.

Like I recently invested in Moozicore. Moozicore is a really good and trustable project for a safe investment.(https://tokensale.moozicore.com/)
